The SOGEVAC vacuum pumps have been manufactured according to the newest technical standards and safety regulations.

3 If not installed properly or not used as directed, dangerous situations or damages might occur. Under certain operating conditions, dangerous situations may occur when running the vacuum pump. If this happens, please contact our local office. Indicate procedures that must be strictly observed to prevent hazards to per-sons. Indicate procedures that must be strictly observed to prevent damage to, or destruction of the appliance. The references to figures, e. g. (2/10) consist of the Fig. No. and the item No. in that order. We reserve the right to alter the design or any data given in these Operating Instructions.

4 When working on the pump system, always observe the Operating Instructions. Disconnect the unit from the power supply before starting any work. Take appropriate precautions to ensure that the pump cannot start. If the pump has pumped hazardous gases, it will be absolutely necessary to determine the nature of the hazard involved and take the appropriate safety precautions. Observe all safety regulations ! Take adequate safety precautions prior to opening the intake or exhaust port. If you send a pump to Leybold , indicate whether the pump is free of sub-stances damaging to health or whether it is contaminated.

5 If it is contamina-ted also indicate the nature of hazard. For this you must use the form we have prepared and which will be provided upon request. A copy of this form, Declaration of Contamination of Vacuum Instruments and Components is reproduced at the end of the Operating Instructions. Please attach this form to the pump, or enclose it with it. This Declaration is required to meet the law and to protect our personnel. Leybold will return any pump received without a "Declaration of Contamination" to the sender's address. The pump must be packaged in such a way that it will not be damaged during shipping, and so that no harmful substances can escape from the package.

6 Safety Information 4300270042_002_C0 - 11/2016 - Leybold1 Design and functionThe SOGEVAC SV300 B are single- stage, oil-sealed rotary vane pumps. The anti-suckback valve, gas ballast valve (optional), exhaust filter, oil return circuit and oil cooling oil are integrated functional elements. The pumps are driven by a directly flanged motor. The rotor mounted eccentrically in the pump cylinder has three vanes which divide the pump chamber into several compartments. The volume of each changes periodically with the rotation of the rotor. As the rotor rotates, the intake portion of the pumping chamber expands and sucks gas through the intake port.

7 The gas passes through the dirt trap and the open anti-suckback valve and enters the pump chamber. As the rotor rotates further, the vane separates part of the pump chamber from the intake port. This part of the pump chamber is reduced, and the gas is compressed. At slightly above atmospheric pressure the gas is expelled from the chamber via the exhaust injected into the pump chamber serves to seal, lubricate and cool the pump. The oil entrained with the compressed gas is coarsely trapped in the oil case by deflection. Then fine filtering occurs in the exhaust filter elements. The proportion of oil in the exhaust gas is thus reduced below the visibility threshold (over 99 % entrapment rate).

8 Oil trapped in the exhaust filters is returned to the inlet chamber via an oil return transfer. To prevent gas flowing at atmospheric pressure from the oil reservoir into the intake port, the oil return line is controlled by a float valve. The oil cycle is maintained by the pressure difference existing between the oil case (pressure above or equal to atmospheric pressure) and the intake port (pressure below atmospheric pressure).The ball bearings are greased for 30 000 hours. A fan running on the pump shaft generates the necessary cooling air. The oil cools down through a radiator. Water cooled pumps with an oil-water heat exchanger and thermostatic valve are also available (as specific variants).

9 By opening the gas ballast valve, a controlled amount of air so called gas ballast is admitted into the pump chamber. This gas ballast prevents con-densation (up to the limit of water vapor tolerance specified in the Technical Data) when pumping condensable gases or vapors. There are different types of gas ballast : - small gas ballast ( 4 m3/h)- standard gas ballast ( m3/h)- large gas ballast ( 15 m3/h)- gas ballast with electromagnetical valve ( 10 m3/h) - See On pumps supplied without gas ballast valve, the valve can be retrofitted. The gas ballast flows are indicative and valid at ultimate 5300270042_002_C0 - 11/2016 - LeyboldWarningCautionUnintentional venting of the vacuum chamber as well as oil suckback when shutting down the pump are prevented by the integrated anti suck-back valve.

10 In applications where an oil suckback must be avoided by all means, it is recommended to install a dedicated Range of use SOGEVAC pumps are designed for pumping of inert gases in the range of rough vacuum, between atmospheric pressure and ultimate pressure of the pump. SOGEVAC pumps are not designed for pumping of agressive, corrosive, flammable or explosive gases. By presence of agressive, flammable, corrosi-ve or explosive gases, contact Oerlikon Leybold Vacuum. These pumps are not designed for working in flammable or explosive environment. In case of doubt, contact Oerlikon Leybold Vacuum for the ATEX pump pumps are not suitable for pumping liquids or media which contain dust.
